22 Jun 2015 | | Abstract: | In this paper, we investigate various $f(R)$-brane models and compare their
gravitational resonance structure with the corresponding general relativity
(GR)-branes. Starting from some preexisting thick brane solutions found in
general relativity (GR-brane), we derive thick $f(R)$-brane solutions such that
the metric, scalar field and scalar potential coincide with those of the
corresponding GR-branes. We find that for branes generated by a single or two
canonical scalar fields, there is no obvious distinction between the
gravitational resonance structures of the GR-branes and corresponding
$f(R)$-branes. Then, we discuss the branes generated by K-fields. In this case,
there might exist huge difference between {the} GR-branes and $f(R)$-branes. | | Source: | arXiv, 1506.6458 | | Services: | Forum | Review | PDF | Favorites | |
